ARRANGEMENT FOR FLEMING.

Specification of Letters Patent.

Patented Sept. 18, 1917.

To all whom-it mayconcem:

Be it .known that we, Dr. KARL Riioxmz and DANIEL PICKEE, subjects ofthe German Emperor and the Queen of the Netherlands, respectively, bothresidents of =Grossbeerenstrasse L9, in the city of Marienfelde, nearBerlin, Germany, have invented new and useful Arrangements for Flaming,of which the following is a specification.

The present invention relates to an improved arrangement for flaming,and consists in the method, including the steps and processes, and theapparatus, comprising the arrangements and combinations, all ashereinafter described and claimed.

The art of flaming as heretofore accomplished, generally employed a blowlamp or torch to which was supplied a gaseous fuel, preferably coal orwater gas. The combustion of such gases is attended with a formation ofwater, as will be understood, and such water deposits upon the surfaceto be treated so as to interfere, and at times positively prevent theprogress of the flaming operation. The presence of water further tendsto reduce the temperature at which the operation is performed, andprohibits that high degree of heat necessary to secure the best results.

Prior methods employing gaseous fuels have been a source of danger fromthe liability of the fuels to explode, and it is to reduce suchliability and to overcome the above disadvantages that the presentarrangement has been devised.

The present method consists primarily in spraying an ignited liquidhydrocarbon under pressure against the surface to be treated, and suchsurface may or may not previously have been coated with a resinoussubstance, such as pitch or varnish. It will be understood thathydrocarbons, such as benzol, petrol, kerosene, and the like, undergocombustion with the formation of little, if any water, and theapplication of the same in the liquid form operates to penetrate theresinous or other coating and to affect the surface to be treated,whereby the coating will flow freely and incorporate itself into thesurface so as to provide a smooth finish.

In the accompanying drawing is illustrated an apparatus for carrying outthe above method, wherein the figure is an elevational view of a vessel,partly in section, and showing the apparatus as applied to treat theinterior thereof.

sameis under the control ofa valvec.

Referring more particularly to the drawing, a designates a vessel,suchas a brewery tank, provided with a manhole, .as shown, and a vent atthe top thereof.

The burner b is-constrncted to receive the liquid hydrocarbon and todirect the same against the interior of the vessel a, and the The liquidhydrocarbon is supplied to the burner I through a tube (Z, preferably ofbrass or copper, of one to two millimeters in diameter, and coiled asshown, to increase the flexibility of the same. The tube (Z is coupledto a valved connection 7 on a tank (2, in which the liquid hydrocarbonis contained, and the tank 6 is provided with a connection 9 for a pump,whereby the same may be placed under suitable pressure. A gage h ispreferably mounted on the tank (2 for indicating the degree of pressuretherein. It will be understood that the supply of hydrocarbon may be cutoff either at the burner I) by means of the valve 0, or at the tank 6 bythe valve f, and the same may contain an amount of fuel sufficient foran entire operation without the necessity of interrupting the operationto replenish the tank; and a single supply of air pressure will be forall purposes sufficient for each charging of said tan It is to beunderstood that the arrangement herein shown and described is notrestricted to the flaming of interior walls of vessels, but may equallywell be applied to exterior walls, ships bottoms, and other surfaces tobe treated; and the method may be employed either in connection with acoating of resinous material previously applied, or not, as desired.

We have illustrated and described preferred and satisfactory process andconstructions, but obviously changes could be made in the hereindescribed method and apparatus which could be used without departingfrom the spirit of our invention.

WVe claim:

1. A device for flaming the inner walls of tanks and the like,especially brewery vessels, in combination, a burner for liquid fuel, areservoir for containing the liquid fuel located outside the vessel tobe flamed, a metallic spirally-wound tube extending through an openingin the vessel and connecting the burner and reservoir, and a valveassociated with said burner and for controlling the passage of theliquid fuel to the same from the reservoir and through said spiral tube,substantially as described.

2. An apparatus of the character de scribed including a burner adaptedto be received through an opening in a tank to be flamed and to bereadily moved about therein by the operator, a reservoir situatedWithout said tank and having means for placing the same under pressure,a thin flexible tube of small diameter having its ends connected to saidreservoir and burner and passing freely through the opening in saidtank, a liquid hydrocarbon placed under pressure in said reservoir andpassing through said tube to said burner, and a valve in said burner forcontrolling the issuance of said hydrocarbon in liquid form, saidissuing liquid hydrocarbon being ignited and directed by the operatoragainst the Walls of the tank, substantially as described.

In testimony, that We claim the foregoing as our invention, We havesigned our names in presence of tWo Witnesses, this 22nd day ofNovember, 1913.
